Thank you for that, a very useful site indeed!!
You don't know whether the name is considered an English one, or a Cornish one at all do you? Though (going on the distribution map) given its preponderance in far west Cornwall and neighbouring Wales it seems reasonable that it is more Briton in origin (or Celtic/Brythonic/Whatever) than English.

"FlammNew" said:
It's English - "Son of Harry" if memory serves - though as Cornish people sometimes took the names of their English Lords, it doesn't mean Harrises are necessarily ethnically English!

Whereabouts are your Harrises from?

[edit] Oops, sorry, didn't see you said Camborne.

Yes, the reading I have done on the name Harris tells me that it is a bit of a blurry one. Both assumed by resident Cornish and brought into Cornwall by English, that is why I asked here hoping people in situ in Cornwall might inform me what the general consensus was on the name...

It is indeed common across the whole south of the blessed isle, but the fact that the emphasis in its concentration is overwhelmingly in Wales and Cornwall seems to imply to me that it is more of a "Celtic" (whatever that word means) surname

I think the Harrises here in Australia came mostly from Camborne and other mining towns

According to the Penguin Dictionary of Surnames, Harris is (as Flamm says), "son of Harry", 26th commonest surname in England and Wales in 1853, 17th in USA in 1939. Family name of the Earls of Malmesbury. Harry is a form of Henry which is, apparently, Normanised Germanic, meaning "home rule" (really), so it isn't Celtic.

The famous Harris family associated with Kenegie (some of whom are still said to haunt the place) were centred at Hayne, Devon, before acquiring Kenegie (up behind Gulval, Pz) from the Arundells.

There are other English Cornish surnames like "Johns", "Williams" etc formed in the same way as "Harris". I've actually got a distant ancestor called "John John" which must have been confusing! Oh, and distant relations called Harris in St Ives in the 1800s.

While the name Harris is of English origin someone called Harris could be in terms of ancestry, as or more Cornish than someone called Trelawney. Surnames such as Thomas, Williams, Johns and Harris etc are considered Cornish as there are so many Cornish people with these names.
